int month=Integer.parseInt( request.getParameter("month"));
int year=Integer.parseInt(request.getParameter("year"));
int count=0;
Vector v1 =new Vector();
String From=null;
String To=null;
Calendar cal = null;
if(month == 12){
     To= month+"/01/"+year;
     year = year+1;
     From = 1+"/01/"+year;
     else
          To=month+"/"+01+"/"+year;
          month=month+1;
          From=month+"/"+01+"/"+year;
     try
     Class.forName("hi");
     Connection Con=DriverManager.getConnection("l","i","i");
     Statement St=Con.createStatement();
     String Query="select c.empid,c.empname,a.fromdate,a.todate, b.ccvalue,b.cclink from pcctrans a , pccval b,pempmast c where b.ccid = a.cc2 and a.eid = c.eid and a.fromdate < '"+From+"' and a.todate > = '"+To+"' order by b.ccvalue ";
     ResultSet rs=St.executeQuery(Query);
     while(rs.next())
     v1.add(rs.getString(1));
     v1.add(rs.getString(2));
     java.sql.Date d= rs.getDate(3);
     java.sql.Date d1= rs.getDate(4);
     cal=new GregorianCalendar(year, month, 01) ;
     if(d.getMonth()<=month && d1.getMonth()>=month)
          count=cal.getActualMaximum(cal.DAY_OF_MONTH );
     System.out.println(count);
     v1.add(d);
     v1.add(d1);
     v1.add(new Integer(count));
